Current Loop Splitters

Current Loop Splitters available from the Laurel QLS series. These units split 1 input signal into 4 independent 4-20 mA current loops.

Current Loop Splitters accept either a 4-20 mA, 1-5 V, 0-5 V, or 0-10 V input signal, and are powered by either 85-264 V ac (for Model QLS-1), or 10-48 V DC (Model QLS-2).

Typical Features include +/-10% zero and span fine adjustments for each output loop. Units can be installed to 35 mm DIN rail with a compact 22.5 mm (0.9 inches) wide case that will easily snap into the DIN rail. Units accept a 4-20 mA, 1-5 V, 0-5 V, or 0-10 V input signal. Independent 4-20 mA outputs(4) proportional to input. The grounds of input and outputs can differ up to +/-10V. There is an indicator LED for each connected output. Opening any output loops does not affect other loops. Outputs can share a common ground.
